Re: Possible to catch undefined sub at "compile" time? (two ways)

use warnings; use strict;
sub monk {}
sub go { mink 123; }

Done.

It also wouldn't be hard to write a module to scan the symbol table for references to undefined subroutines after the main script finished compiling and right before it starts running. I believe diotalevi(?) already wrote a module to report references to undefined subroutines.

I didn't write B::Lint. It comes with your perl. ⠤⠤ ⠙⠊⠕⠞⠁⠇⠑⠧⠊	[reply]

I guess diotalevi's solution is what I was looking for: `> perl -MO=Lint -c mink.pl Nonexistant subroutine 'mink' called at mink.pl line 4 mink.pl syntax OK` [download] It's a pity that it doesn't work on Windows to add '-MO=Lint' in the shebang line. Thanks everyone for your help and/or entertaining suggestions.	[reply] [d/l]
